Cisco Systems is warning customers of a critical vulnerability affecting three of its TelePresence MCU platform models.
A vulnerability in Cisco’s meeting server software allows a remote attacker to masquerade as legit user.
Networking giant Cisco issued five security bulletins this week with two critical bugs allowing remote execute code.
Effective October 18, 2011, Cisco has replaced the existing RSS feeds for Cisco Security Advisories. The new RSS feeds for Cisco Security Advisories are available at http://tools.cisco.com/security/center/psirtrss10/CiscoSecurityAdvisory.xml and http://tools.cisco.com/security/center/psirtrss20/CiscoSecurityAdvisory.xml. The existing RSS feeds will continue to function until November 19, 2011. They will not receive updates after this date.
A denial of service (DoS) vulnerability exists in the Cisco Video Surveillance IP Cameras 2421, 2500 series and 2600 series of devices. An unauthenticated, remote attacker could exploit this vulnerability by sending crafted RTSP TCP packets to an affected device. Successful exploitation prevents cameras from sending video streams, subsequently causing a reboot. The camera reboot is done automatically and does not require action from an operator.
Cisco Unified Communications Manager contains a directory traversal vulnerability that may allow an unauthenticated, remote attacker to retrieve arbitrary files from the filesystem.
Cisco Unified Contact Center Express (UCCX or Unified CCX) and Cisco Unified IP Interactive Voice Response (Unified IP-IVR) contain a directory traversal vulnerability that may allow a remote, unauthenticated attacker to retrieve arbitrary files from the filesystem.
Multiple buffer overflow vulnerabilities exist in the Cisco WebEx Recording Format (WRF) player. In some cases, exploitation of the vulnerabilities could allow a remote attacker to execute arbitrary code on the system with the privileges of a targeted user.
Cisco Security Agent is affected by vulnerabilities that could allow an unauthenticated attacker to perform remote code execution on the affected device. These vulnerabilities are in a third-party library (Oracle Outside In) and are documented in CERT-CC Vulnerability Note VU#520721 at http://www.kb.cert.org/vuls/id/520721
The Cisco Show and Share webcasting and video sharing application contains two vulnerabilities.
